Weidmueller TR BD AITB BB 2RCD W/O TS

TR BD AITB BB 2RCD W/O TS refers to an electrical distribution board that includes two Residual Current Devices (RCDs) and an Automatic Insertion Type Breaker (AITB) for overcurrent and leakage current protection. The "2RCD" means two RCDs are included, providing dual protection, while "W/O TS" stands for "Without Test Switch," indicating the RCDs do not have a built-in test switch. This configuration is typically used in environments where high safety standards are needed, but without the extra feature of a test switch for the RCDs.
